Mr. Gianopulos shortly stabilized the 1910s-era studio — repairing relationships with filmmakers and producers, constructing a thriving tv division from near-scratch, and restoring Paramount to profitability.

He was ousted on Monday, along with his standing as the consummate Hollywood insider having curdled right into a legal responsibility, not less than to ViacomCBS, the conglomerate that owns Paramount, the place streaming, streaming, streaming is the brand new forex of the realm.

But the ouster rattled the movie enterprise nonetheless. It was seen by some as barbarous — custom holds that senior statesmen get to write down their very own endings. And it added to a altering of the guard: Ron Meyer, a longtime movie energy at Universal, left final 12 months amid a intercourse scandal, and Alan F. Horn, the chief artistic officer at Walt Disney Studios, is extensively anticipated to retire within the coming months.

Bob Bakish, the chief government of ViacomCBS, stated in an announcement that the management change would “build on Paramount’s strong momentum, ensuring it continues to engage audiences at scale while embracing viewers’ evolving tastes and habits.” He stated Mr. Robbins was an “expert” at creating franchises by “leaning into the unique strengths of new and established platforms.”

For many movie business stalwarts, Mr. Robbins is an affront to their identities; he comes from tv, stated whereas holding one’s nostril. Mr. Robbins has expertise as a film producer and director.

“There is no movie business anymore!” Mr. Robbins was quoted by Fast Company as saying in 2013. “The model’s broken, and I see that as an opportunity.”

Mr. Robbins was named president of Nickelodeon, which is additionally owned by ViacomCBS, in 2018. He has grow to be recognized inside Viacom as a plain-spoken, never-say-die futurist who believes that Paramount+, the corporate’s comparatively small streaming service, should be supercharged.

One such present, a reboot of “iCarly,” has been a success for the streaming service.

Mr. Gianopulos, or “Jim G” as everybody in Hollywood refers to him, will stay a advisor till the top of the 12 months, ViacomCBS stated. “Jim is nothing less than legendary in this business, and I am humbled and grateful to him for his years of mentorship and friendship,” Mr. Robbins stated in an announcement.

Mr. Robbins will proceed to steer Nickelodeon, ViacomCBS stated. But he is not going to get all of Mr. Gianopulos’s portfolio; Paramount Television Studios will now report back to David Nevins, the chairman and chief government of Showtime Networks.
